charmap(5) File Formats Manual charmap(5)
charmap - character set description file
A character set description (charmap) defines all available
characters and their encodings in a character set. localedef(1)
can use charmaps to create locale variants for different
character sets.
Syntax
The charmap file starts with a header that may consist of the
following keywords:
<code_set_name>
is followed by the name of the character map.
<comment_char>
is followed by a character that will be used as the
comment character for the rest of the file. It defaults
to the number sign (#).
<escape_char>
is followed by a character that should be used as the
escape character for the rest of the file to mark
characters that should be interpreted in a special way.
It defaults to the backslash (\).
<mb_cur_max>
is followed by the maximum number of bytes for a
character. The default value is 1.
<mb_cur_min>
is followed by the minimum number of bytes for a
character. This value must be less than or equal than
<mb_cur_max>. If not specified, it defaults to
<mb_cur_max>.
The character set definition section starts with the keyword
CHARMAP in the first column.
The following lines may have one of the two following forms to
define the character set:
<character> byte-sequence comment
This form defines exactly one character and its byte
sequence, comment being optional.
<character>..<character> byte-sequence comment
This form defines a character range and its byte sequence,
comment being optional.
The character set definition section ends with the string END
CHARMAP.
The character set definition section may optionally be followed
by a section to define widths of characters.
The WIDTH_DEFAULT keyword can be used to define the default width
for all characters not explicitly listed. The default character
width is 1.
The width section for individual characters starts with the
keyword WIDTH in the first column.
The following lines may have one of the two following forms to
define the widths of the characters:
<character> width
This form defines the width of exactly one character.
<character>...<character> width
This form defines the width for all the characters in the
range.
The width definition section ends with the string END WIDTH.
/usr/share/i18n/charmaps
Usual default character map path.
POSIX.2.
The Euro sign is defined as follows in the UTF-8 charmap:
<U20AC> /xe2/x82/xac EURO SIGN
